Description

This is a printable version of thingiverse.com/thing:4017 which is a derivative of thingiverse.com/thing:1351

I do not have a heated build platform and I am pretty sure this will warp if you try to print it without. Like before, you will need to modify your weird dino or something if you want to use this with a stepper motor. So with that being said, this is experimental, but in theory it should work.

I have also included the Sketchup file.

Thanks goes to dsralph for the idea to print this.

EDIT: Updated STL files. Due to stupid STL export from Sketchup, the others were not goodly... This are much happier! :D

Instructions

1. Print one of each STL. You will need to make a plunger thing to push against the plastic like the original.

2. Put it together.
(Self explanatory, but if you need help head over to thingiverse.com/thing:1351)

3. Mount it to your Dinos.

4. Start extruding on your new Printed Drop-in Paxtruder!!

I gave it a shot this evening, unsuccessfully. A few problems:

- According to MeshLab and Blender, there are an enormous number of duplicate vertices in the STL files. The largest of the files has over 5,000 duplicates.
- Even after removing the duplicates, skeinforge took a while to process the files. The biggest of the bunch took almost ten minutes on my P
C. Furthermore, it wouldn't show on skeinview. (It displayed only a blank screen.)
- I need a heated build platform and the raft plugin. I realized the need for the raft plugin the hard way: I couldn't find the happy medium between prints that peeled and prints that stalled out. (I blew out the extr
uder's retaining ring in the process.) Of course, using the raft meant pushing the files through skeinforge again.
- The biggest of the files is a two-hour print job. I got about halfway through when my printer stalled out once more. Hoping to run for two hours straight was probably a pipe dream.
-
When I scraped the partial print off the build platform, I realized that it was missing some details. The outline of the shape was fine and the holes were present, but none of the surface grooves were showing. This might be another problem stemming from the large file sizes.
- At least on my printer
, it appears that the holes on the object don't quite line up with the dino. They look to be short by about 1.5 mm. The files may need to be scaled up about 2% before printing.

In short, this might work, but some changes are needed to the files.

Yeah turns out my STL exporter out of sketchup was not very hood at all.. I'll fix the files and reupload when I get home from work.

After another look, it appears the details were there after all. My other comments still stand.
